MANIFOLD DUPLICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 728,601, dated May 19,1903.

Application filed October 31, 1902. Serial No. 129.583. (No model.)

To all whom it may concern:

Be it known that I, HENRY H. NORRINGTON, acitizen of the United States,residing at West Bay City, county of Bay, State of Michigan, haveinvented a certain new and useful Improvement in Manifold DuplicatingDevices, of which the following is a specification, reference being hadto the accompanyingdrawings, which form a part of this specification.

My invention has for its object a new and improved manifold duplicatingdevice; and it consists of the construction, combination, andarrangement of devices hereinafter described and claimed, andillustrated in the accompanying drawings, in which- Figure 1 is a Viewin perspective, illustrating features of my new invention. Fig. 2 is apartial plan view of the same, illustrating features of my invention.Fig. 3is a view in section on the line 3 3, Fig. 2, and showingv partsin elevation. Fig. 4 is a View in section on the line 4 4, Fig. 2. Fig.5 is a view in section on the line 5 5, Fig. 3.

The object of my present invention is to provide a manifold duplicatingdevice of simple and economical construction and of superior efficienoy.

Among the objects of my present invention I contemplate moreparticularly providing my improved duplicating device with acarbon-sheet mounted upon a roller, the carbonsheet being supplied tothe trade so mounted, dispensing with the necessity of engaging acarbon-sheet with the roller when it becomes necessary to renew thecarbon-sheet. The carbon-sheets being supplied to the trade mounted uponrollers, in order to renew the carbon-sheet simply requires theinsertion of the roller upon which the fresh carbon-sheet is mounted insuitable brackets, as hereinafter set forth, the aim of my presentinvention being to facilitate the engagementof such a roller in thedevice, the removalof a'roller therefrom when its carbon-sheet hasbecome worn, and the ready adjustment of the device permitting thecarbon-sheet to be unrolled and the roller to be held rigidly in placein any desired position of adjustment.

I carry out my invention as follows:

In the drawings, a, represents any suitable base, upon which'may beengaged in any suitable manner a block or sheets 1), upon which theduplicate copy is to be made. A roller 0 is provided, upon which a sheetof carbon is mounted,(indicated at 61,) the sheet of carbon beingpermanently engaged with the roller in any desired manner. Toward oneedge of the base is a track 6. To support the roller, I providebracketsfand g,one of the said brackets,

as the bracketf, having a fixed engagement "upon the base in anysuitable manner, as by a holding the movable bracket from verticaldisengagement from the track, the track is constructed toward one endthereof with an elongated orificej, the arm 1' being provided with aheaded pin, (indicated at 70,) the base a being countersunk, asindicated at Z, to receive the head of the pin, the stem of the pinprojecting through the orifice j. The brackets are constructed towardtheir upper ends to receive the ends of the roller, as in recesses m andn, in the corresponding brackets. To hold the two brackets in desiredposition of adjustment the one relative to the other, I provide athreaded rod, (indicated'at m) which may be provided witha milled head gat one end thereof, the adjacent end of the rod being passed through themovable bracket 9 and having a threaded engagement in the oppositebracket, as indicated at 1". When itis desired to insert a carbon-rollerinto the brackets, the rodp will be unscrewed, permitting the bracket gto be moved away from the opposite bracket, permitting the roller to beinserted in the sockets of the brackets. The rod may then be screwed upas may be required, forcing the movable brackettoward the adjacentbracket to hold the roller in place and to cause the two brackets tobind suitably upon the adjacent ends of the roller to hold the rollerfrom accidental rotation,

thereby holding the roller in any given position of adjustment. When itis desired to unroll the carbon-sheet, the rod 19 is simply loosened,permitting the sheet to be turned out the required distance, when byscrewing up said rod the roller will be held in given position. It ispreferred to have the carbonsheet passed under the rod 19, the rod thusserving to hold the adjacent end of the sheet more firmly down upon thesheets I). The rod 19 may also serve as a guide in placing the mainsheet upon the carbon-sheet and over the sheets to receive the duplicateimpression.

It will be understood that in the operation of the device thecarbon-sheet is drawn down over the sheets I). The sheet upon which themain copy is to be made is then placed over the carbon-sheet and thedesired inscription made thereupon. The main copy being removed, thecarbon-sheet may be lifted up from the blanks b and the duplicate copydetached. The carbon-sheet then falls into position over the blanksheets I), and the device is again in readiness for making anotherduplicate copy. As already observed, when a given portion of thecarbon-sheet has become worn it may be torn oif, the rodp being loosenedup, permitting the drawing out of a fresh portion of the carbon-sheetsover the sheets I), the rod 19 being screwed up again to hold the rollerin fixed position in the brackets.

The device is obviously simple, not liable to get out of order, and maymost readily be operated.

While I prefer to employ a carbon-sheet furnished to the trade alreadymounted upon a roller, I do not limit myself solely thereto, asmyinvention contemplates as coming with in its scope the employment ofany roller with which the carbon-sheet may be engaged,

held in place by suitable supports, one of said supports adjustabletoward and from the othersupport.

What I claim as my invention is- 1. In a duplicating device thecombination of a base, a roller extending across one end of the base tohold a roll of carbon-paper, supports upon opposite edges of said baseat one extremity thereof to hold the roller, one of said supportsadjustable transversely of the base toward and from the other supporttopermit the insertion and removal of the roller, and means to unite saidsupports and to hold said supports in adjusted position.

2. In a duplicating device the combination of a base, a roller to hold aroll of carbonpaper, supports for said roller, one of said supportsadjustable toward and from the other support, and a rod having athreaded engagement with one of said supports to unite said supports.

3. In a duplicating device the combination of a base, a roller to hold aroll of carbonpaper, brackets to support the roller, one of saidbrackets adjustable toward and from the other bracket, and a rod passedthrough one of said brackets and having a threaded engagement with theother bracket.

4. A duplicating device having in combination a base, a track upon thebase provided with an elongated slot, a roller to hold a roll ofcarbon-paper,bracke ts to support the roller, a rod passed through oneof said supports and having a threaded engagement with the othersupport, one of said brackets provided with an arm having a movableengagement lengthwise of said track.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
